On Complex Gamma-Function Integrals
Sergey E. Derkachov, Alexander N. Manashov
It was observed recently that relations between matrix elements of certain operators in the spin chain models take the form of multidimensional integrals de…
From Principal Series to Finite-Dimensional Solutions of the Yang-Baxter Equation
Dmitry Chicherin, Sergey E. Derkachov, Vyacheslav P. Spiridonov
We start from known solutions of the Yang-Baxter equation with a spectral parameter defined on the tensor product of two infinite-dimensional principal series representations of th…
Integrability of the evolution equations for heavy-light baryon distribution amplitudes
V. M. Braun, S. E. Derkachov, A. N. Manashov
We consider evolution equations describing the scale dependence of the wave function of a baryon containing an infinitely heavy quark and a pair of light quarks at small transverse…
Yang-Baxter operators and scattering amplitudes in super-Yang-Mills theory
D. Chicherin, S. Derkachov, R. Kirschner
Yangian symmetry of amplitudes in super Yang-Mills theory is formulated in terms of eigenvalue relations for monodromy matrix operators. The Quantum Inverse Scatter…
Baxter operators with deformed symmetry
D. Chicherin, S. Derkachov, D. Karakhanyan +1
Baxter operators are constructed for quantum spin chains with deformed symmetry. The parallel treatment of Yang-Baxter operators for the cases of undeformed, trigonometri…
Conformal algebra: R-matrix and star-triangle relation
D. Chicherin, S. Derkachov, A. P. Isaev
The main purpose of this paper is the construction of the R-operator which acts in the tensor product of two infinite-dimensional representations of the conformal algebra and solve…
